CyberKnife radiosurgery for an intracardiac metastasis

Abstract

Figure A compact linear accelerator is mounted on a six-joint robotic arm, which can move freely around the patient. Two kilovoltage x-ray sources are positioned orthogonally for near 'real-time' target imaging. The infrared Synchrony camera can monitor chest-wall movement via light-emitting diodes placed on the patient's chest.
